Association between visual attention and parent-reported social problems in pediatric cancer survivors.

Social deficits in pediatric cancer survivors have been well documented and have been linked to neurocognitive late effects, particularly attention deficits. The purpose of this study was to examine the association between components of attention, both parent-report and a performance-based measure, with parent-reported social functioning in survivors of pediatric cancer. The study included data from outpatient neuropsychological evaluations of 76 survivors of pediatric cancer.

Differential Diagnosis of Autism Spectrum Disorder Versus Language Disorder in Children Ages 2 to 5 Years: Contributions of Parent-Reported Development and Behavior.

Early diagnosis of autism spectrum disorder (ASD) has focused on differentiating children with ASD from neurotypical children. However, many children presenting with concern for ASD are ultimately diagnosed with language disorder (LD). This study aimed to identify differences in parent-rated development and behavior among children ages 2 to 5 years presenting with concern for ASD who were diagnosed with either ASD or LD.

Visual Attention and Math Performance in Survivors of Childhood Acute Lymphoblastic Leukemia.

Objective: Attentional and academic difficulties, particularly in math, are common in survivors of childhood acute lymphoblastic leukemia (ALL). Of cognitive deficits experienced by survivors of childhood ALL, attention deficits may be particularly responsive to intervention. However, it is unknown whether deficits in particular aspects of attention are associated with deficits in math skills.

Magnetoencephalography shows atypical sensitivity to linguistic sound sequences in autism spectrum disorder.

Neuroscientific evidence points toward atypical auditory processing in individuals with autism spectrum disorders (ASD), and yet, the consequences of this for receptive language remain unclear. Using magnetoencephalography and a passive listening task, we test for cascading effects on speech sound processing. Children with ASD and age-matched control participants (8-12 years old) listened to nonce linguistic stimuli that either did or did not conform to the phonological rules that govern consonant sequences in English (e.

Visual attention shifting in autism spectrum disorders.

Introduction: Abnormal visual attention has been frequently observed in autism spectrum disorders (ASD). Abnormal shifting of visual attention is related to abnormal development of social cognition and has been identified as a key neuropsychological finding in ASD. Better characterizing attention shifting in ASD and its relationship with social functioning may help to identify new targets for intervention and improving social communication in these disorders.

Neural synchrony examined with magnetoencephalography (MEG) during eye gaze processing in autism spectrum disorders: preliminary findings.

Background: Gaze processing deficits are a seminal, early, and enduring behavioral deficit in autism spectrum disorder (ASD); however, a comprehensive characterization of the neural processes mediating abnormal gaze processing in ASD has yet to be conducted.

Methods: This study investigated whole-brain patterns of neural synchrony during passive viewing of direct and averted eye gaze in ASD adolescents and young adults (M Age  = 16.6) compared to neurotypicals (NT) (M Age  = 17.

Impaired prefrontal gamma band synchrony in autism spectrum disorders during gaze cueing.

Orienting to eye gaze is a vital social skill that is absent or developmentally delayed in autism spectrum disorders (ASD). Neural synchrony in the gamma frequency band is believed to be involved in perceptual and cognitive functions such as eye-gaze processing, and has been found to be abnormal in ASD. The current study used magnetoencephalography to measure neural synchrony in the gamma frequency band in neurotypicals (n=8) and individuals with ASD (n=10) while performing a directional eye-gaze processing task.

Persistence, diagnostic specificity and genetic liability for context-processing deficits in schizophrenia.

Context-processing deficits have been shown in schizophrenia during first-episode, medication-naïve status, that persist after short-term antipsychotic treatment and also in first-degree relatives of individuals with schizophrenia. To confirm longer term persistence of deficits, we examined schizophrenia patients (n=63) during first-episode, medication-naïve status through to one-year follow-up, compared to healthy control (n=83) and non-schizophrenia psychosis comparison (n=47) groups, as well as unaffected first-degree relatives of individuals with schizophrenia (n=31). Context-processing ability was assessed by performance on the AX-CPT (Continuous Performance Test) at baseline, 8 weeks, 6 months, and 1 year (relatives only at baseline).
